Description: CloudFront Functions Demo

# This example shows how to use CloudFront, CloudFront Functions, and CloudFormation.
# In this simple example we setup CloudFront so that on any request we redirect to another site.
# While basic, this example can be expanded to provide typical redirect scenarios, based
# on the event passed to the function.

# This example written by Mike Roberts (https://twitter.com/mikebroberts), Symphonia.
# For more ideas about using AWS more effectively,see our blog at https://blog.symphonia.io/
